To all whom it may concern:

Be it known that I, GEORGE E. Mrr'rmenn, a citizen of the United States,residing at Cleveland Heights, Cleveland, in the county of Cuyahoga andState of Ohio, have mvented certain new and useful Improvements inFastening and Clamping Rings,

of which the following is a specification,

in its use entirely by hand.

Another object of the invention is to pro-- videa novel form andconstruction of clamping and fastening ring which can be manufactured ata considerable saving over those fastening rings now in use.

Another and further object of the invention is to provide a novel formof ring which can be operated entirely by hand for fasten ing andclamping the lids 0r covers of receptacles.

A still further object of the invention is to provide a ring of thecharacter described which is additionally provided with a looking means.

Another and further object of the inven tion is to provide a ring of thecharacter described which is simple of construction and operation, cheapof manufacture and highly efl'icient in use.

Other further objects, novel features of construction and, improvedresults of the invention will appear from the following description andaccompanying drawings In the drawings: Figure 1 is a fragmentary view inelevation showing the application of the ring to a receptacle. I Figure2 is a fragmentary vertical sectional view of Fig. 1, the section beingtaken centrally through the overlapping ends of the ring and the lockingdevice.

Fi 3 is a fragmentary top plan view showing the first step in applyingthe ring to a receptacle.

.Fig. 4 is a fragmentary top plan view Application filed March 25, 1925.Serial No. 18,171. 7

showing the ring applied to a receptacle and ready to be locked inplace.

To those skilled in the art it is well known that in the-manufacture ofreceptacles it is important that there be provided a cover attaching orfastening construction which is s1mple and quick in operation and at thesame time one which is satisfactory and eificle'nt when in use. Theabove features must be of a character which will not make themanufacturing cost prohibitive. There are certain rules laid down by therailroads in respect to containers carried by them and all containersmust meet with and comply to these railroad standards. In the drawings Ihave shown'tmy improved fastening and clamping ring as applied to apaint pail but it will be readily understood that the principles of myinvention can be applied to other receptacles without departing from'the spirit of the inventlon. p

The paint pail body is designated in the drawings as A, thepaint pailcover or lid as B, the clamping and fastening ring as C and the lockingmember as D.

The paint pail or container A at its upper end is provided with aninward bend or crimp 5 which curves upwardly and outwardly as at 6 andterminates in an approximately flat or horizontal edge or flange 7.

The container cover or lid B comprises a bottom 8 surrounded by upwardlyand slightly outwardly extending walls 9 terminating in the horizontalcircumferential edge or flange 10. y

.In applying the lid to the container the lid bottom 8 and side walls 9extend downwardly into the container while the container flange 7 andlid flange 1O are adapted to seat one upon the other. Inasmuch as thecontainer being described is for transportation of a liquid arubberasket'll is-jinterposed between the flanges be readily understoodhowever that in the event the container is to be used for thetransportation of dry materialthe'rubber gasket 11 can be eliminated.

The lockingmember D is formed as an integral part of the flange 10 ofthe cover I and extends in a horizontal plane outwardly from the coverflange as clearly appears in Figs. 3 and 4 of the drawing. This lockingand 10. Itwill 5 sure that there will member in reality is a lug havinga curved -or are shaped. outer edge 12, and an approximately straightedge 13 which adjacent its connection with'the id flan e 10 isprovidedwith an inwardly struc notch 14:. The operation of the lockingmember-W111 be hereinafter described.

The ring 0 is V-shaped in cross section, as clearly ppears in Figure 2of the drawings, the apex of the V being rounded rather than meeting anacute angle while one side 15 of the V 1s slightly wider or longer thanthe opposit" side or wall 16 of the V. In application the V lies uponits side and hereinafter the wall 15 will be referred to as the upperwall and the wall 16 as the lower wall. The ring is of a length slightlygreater than the circumference of the receptacle to which it is to beapplied and hence the ring ends 17 and 18 overlap when applied to thereceptacle, as clearly appears 1n Figures 1, 3 and 4 of the drawings.

Both of t e ring ends 17 and 18 are provided with slots or openings 19adjacent their ends. These slots or openings are formed by cutting out aportion of the rounded apex of the ring. A short wall or ends 20 is leftbetween the ends of the ring and the notches 19. As clearly appears inthe drawing the notches 19 are of sufiicient len h to receive thelocking lug D.

he 0 ration or application of the ring is as fol ows: After t e lid orcover B has been placed on the receptacle A in the manner shown in Fiure 2 of the drawings, one end of the rin is positioned as shown in Fig.3 of the rawings with the locking lug D extending outwardly through therin notch 19. Throughout the remainin lengt of the ring it is positionedto have tween its upper and lower walls 15 and 16 the flanges 7 and 10of the receptacle and lid respectively. It will then be ound that theunattached end of the ring will assume the position shown in Fig. 3 ofthe drawin with the locking lug D extending partial y through the ringnotch 19.

It will now be-seen due to the curved or are form of the locking lugedge 12 that by pushing the ring downwardly or inwardly will cause thering to tightly clamp the overlapping flanges of the receptacles andcover together. I

When the ring is in place it will assume the position shown in F1gure 4of the drawings. The ring ends are overlapped with the end wall 20 ofone ring end in the docking lug notch 14 while a portion 21 of the apexof the opposite ring ends enters the notch and overlaps the end wall 20heretofore mentioned.

The ring is now fastened and place, securely container body clamped inclamping and fastening the and cover together. To asbe no displacementof the ring the locking lug D is now bent downwardly and inwardly. asappears in Figure 2 of the drawings with the resultthat the clamping andfastening ring is securely locked into position.

To guard against unlawful tampering with the pail contents andfto complywith this ruling of the railroads\ it is intended that the locking lug Dbe provided with an opening 22 adapted to receive the common form oflead seal 23 after the ring has been positioned upon the container andits cover.

To comply with the further ruling of the railroads the construction ofboth the container and the locking lug is such that the extreme outeredges of the lid fastenin construction, which is the locking lug asclear] appears in Figure 2 of the drawings, lies within the verticalplane of the container side walls 24.

From the foregoing it will be seen that I have provided a fastening,clamping and locking ring which can be applied entirely by hand and canbe as readily removed in the same manner. This is readily apparent whenit is pointed out that the locking lug D is of a thickness of metalwhich will permit its being bent by the thumb or fingers of the hand. Byreason of the construction heretofore described I have eliminated thenecessity of the use of a screw-driver or other tool to effect thelocking or unlocking of the container cover.

Having thus described my invention what I claim and desire to secure byLetters Patent is 1. A device for clamping and fastening the cover of acontainer in place, comprising a ring provided with o enin s, a lockingand clamping lug carried by t e cover and having a curved outer edge,and said lug adapted to enter and en ings, whereby the application ofthe ring oi'er the lug clamps and fastens the ring in p ace.
